11.5 Functional Groups

2 Functional Groups Functional groups are
A characteristic feature of organic molecules that behave in a predictable way. Composed of an atom or group of atoms. Groups that replace a H in the corresponding alkane. A way to classify families of organic compounds.

3 Some Functional Groups

4 Alcohols and Ethers An alcohol contains the hydroxyl (-OH) functional group. An ether contains an oxygen atom bonded to two carbon atoms –C–O–C– .

5 More Functional Groups

6 Aldehydes and Ketones An aldehyde contains a carbonyl group (C=O), which is a carbon atom with a double bond to an oxygen atom. In a ketone, the carbon of the carbonyl group is attached to two other carbon atoms.

7 Carboxylic Acids and Esters
Carboxylic acids contain the carboxyl group, which is a carbonyl group attached to a hydroxyl group. O || —C—OH In an ester, the H in the carboxyl group is replaced by a carbon.

8 Amines and Amides In amines, the functional group is a nitrogen atom.
